Claims

[Scope of utility model registration request]

In an automobile muffler comprising an exhaust pipe with a large number of holes formed on the circumferential surface, an outer pipe arranged around the exhaust pipe, and a sound deadening material housed between these pipes, the exhaust pipe has a In the above-mentioned flow side portion located on the engine side, the hole formed is an exhaust gas receiving hole in which the cut end protruding toward the inside of the pipe faces the flow of exhaust gas when the cut is made from the outside of the exhaust pipe. The sound deadening material is formed into a cut-shaped hole having a piece, and the downstream part is formed as a hole through which the inside and outside pass, and the sound deadening material is filled with a stainless steel mesh made of thin stainless steel wires woven into a mesh. An automobile muffler characterized by:
